If 80% of M is equal to 50% of N and N ≠ 0 what is N/M equal to?

M/N=5/8  or 62.5%

Step-by-step explanation:

when turning the word problem to equation...

since you have the value of M in terms of N you should substitute M by 5N/8.

if you want it as a percent just multiply 5/8 by 100%.

=62.5%

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
